IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 178,397, dated June 6,1876; application filed March 8, 1876.

To all 'w/Lom it' may conce'n 1 Be it known that l, CHARLES O. BABOOOK,of Kirkwood, county of 'Warren, and State of lllinois, have inventedcertain new and useful Iinprovements in Railway-Car Couplings, of whichthe following' is a full, clear, and exact description, reference beinghad to the accompanying' drawing, making part of this specification, andin which Figure 1 is a horizontal sectional view in the line w x in Fig.2; and, Fig'. 2, a Vertical sectional view in the line a: x in Fig. 1,of a car-coupling` embodying` my invention. Fig. 3 is a detail view-atopview of the couplinglink and sectional View of the conpling-pin.

Referring' to the parts by letters, A A represent Athe adjacent ends oftwo draw-heads, constructed with wide mouths a, with triangular holesaf' for the coupling-pin, and with angular projecting parts a in theirrear ends. B is a stud projecting forward from the central portion ofthe projection a in the rear side of the opening in the draw-head. It islocated about midway ofthe heig'ht ofthe opening, and 'serves to holdthe end of the link down, and thereby keep the link in a horizontalposition ready for coupling. O is the coupling-pin, triangular in itscross-section, and each ot' its sides grooved longitudinally, as plainlyshown a't Figs. 1 and 3. D is the coupling-link, forined as shown atFig. 3, of two side bars, D', connected at one end, d, in such mannertasto leave a contracted opening, d', for coupling to an ordinary draw-headwith an ordinary round pin. The open end of the link D is formed, asshown at Figs. 1 and 3, with a projection or'head, e, on the inner sideof each bar D', the forward faces d of which are inclined, as shown inthe drawing's, and in such manner that when the link approaches thetriangular pin O, as shown at Figs. 1 and 2, the pin O being' held Withone angle forward by the holes a', the heads e will be separated by theinclined sides or faces of the pin (J, and allow the rear sides e' ofthe heads e to pass the coupling-pin, when the arms D' will closetogether and forin the couplin g, as shown at Fig'. 3.. To increase thesecurity of the coupling, the rear Shoulders or sides e' of the heads eare curved corresponding'ly with thecurved faces of the. pin O, (seeFig. 3,) so that when the shoulders e' are drawn against the pin thecurved face of the pin will tend to hold the heads e together. Fig. 2shows the manner ot' seating the closed end of the link D beneath thestud B in one draw-head, for the pnrpose of snstaining it in position toenter the other. Fig. 1 shows how in entering' the other the couplingwill be eft'ected automatically. The pin O may be withdrawn to unconplethe draw-heads.

What I claim as new is- The link D, having spring-heads e on one end andopening d' in the other end, and' arranged to operate in combinationwith the (lraW-heads A,having` studs B, and triangular holes a', andwith the triangular pins O, substantially as and for the pnrposespecified.

In testimony that I claim the foregoing as my invention, I have heretoaflixed my signature this 12th day of February, 1876, in presence of twowitnesses.

CHARLES OMNER BABOOOK.
